Google Cloud Firestore Extension

Add data

The following ExtensionCallout policy adds a document called freewill@example.com to a users collection. The data property specifies the fields and values of the new document.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ConnectorCallout async="false" continueOnError="true" enabled="true" name="Add-User-Data">
    <DisplayName>Add User Data</DisplayName>
    <Connector>my-cloud-firestore-extension</Connector>
    <Action>setDocument</Action>
    <Input><![CDATA[{
        "colName" : "users",
        "docName" : "freewill@example.com",
        "data" : {
            "firstName": "Will",
            "lastName": "Witman",
            "address": "270-8243 Tempor St.",
            "city": "Fort Worth",
            "region": "TX",
            "postalCode": "86519",
            "email": "freewill@example.com",
            "username": "freewill444"
        }
    }]]></Input>
</ConnectorCallout>

Get data

In this example, the ExtensionCallout policy retrieves the value of the freewill@example.com document from the users collection. Here, the <Output> element's parsed attribute is set to false so that the returned result will be JSON as a string, rather than JSON parsed into an object. For more, see the <Output> element reference.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ConnectorCallout async="false" continueOnError="true" enabled="true" name="Get-User-Data">
    <DisplayName>Get User Data</DisplayName>
    <Connector>straut-cloud-firestore-extension</Connector>
    <Action>getDocument</Action>
    <Input><![CDATA[{
        "colName" : "users",
        "docName" : "freewill@example.com"
    }]]></Input>
    <Output parsed="false">firestore.userdata.retrieved</Output>
</ConnectorCallout>

The following Assign Message policy uses the value of the variable storing the extension's response to assign the response payload.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<AssignMessage name="CopyUserDataToResponse">
    <DisplayName>Copy User Data To Response</DisplayName>
    <AssignTo type="response" createNew="false"/>
    <Set>
        <Payload contentType="application/json">{firestore.userdata.retrieved}</Payload>
    </Set>
</AssignMessage>

Delete data

In this example, the ExtensionCallout policy deletes the lizzie@example.com document from the users collection.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ConnectorCallout async="false" continueOnError="true" enabled="true" name="Delete-User-Data">
    <DisplayName>Delete User Data</DisplayName>
    <Connector>my-cloud-firestore-extension</Connector>
    <Action>deleteDocument</Action>
    <Input><![CDATA[{
        "colName" : "users",
        "docName" : "lizzie@example.com"
    }]]></Input>
</ConnectorCallout>

Query data

In this example, the ExtensionCallout policy queries a cities collection. Query results are filtered by the state and population fields. Here, the <Output> element's parsed attribute is set to false so that the returned result will be JSON as a string, rather than JSON parsed into an object. For more, see the <Output> element reference.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ConnectorCallout async="false" continueOnError="true" enabled="true" name="Query-City-Data">
    <DisplayName>Query City Data</DisplayName>
    <Connector>cloud-firestore-extension</Connector>
    <Action>query</Action>
    <Input><![CDATA[{
        "colName":"cities",
        "queryArray":[
          ["state", "==", "CA"],
          ["population","<",1000000]
        ]
    }]]></Input>
    <Output parsed="false">compound-query-output</Output>
</ConnectorCallout>

The following Assign Message policy uses the value of the variable storing the extension's response to assign the response payload.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<AssignMessage name="CopyQueryResultsToResponse">
    <DisplayName>Copy Query Results To Response</DisplayName>
    <AssignTo type="response" createNew="false"/>
    <Set>
        <Payload contentType="application/json">{firestore.querydata.retrieved}</Payload>
    </Set>
</AssignMessage>

Syntax

<Input><![CDATA[{
  "colName" : "firestore-collection-name",
  "queryArray" : "queryArray": query-condition-array
}]]></Input>

Example

In this example, the queryArray parameter specifies two conditions on which to filter the cities collection specified by the colName parameter.

A query that includes multiple conditions must be supported in Cloud Firestore by a composite index. For more information, see Index types in Cloud Firestore.

<Input><![CDATA[{
  "colName":"cities",
  "queryArray":[["state", "==", "CA"],["population","<",1000000]]
}]]></Input>

At runtime, this action is interpreted as a query such as the following:

Select all of the cities where state = 'CA' and population < 1000000
